Answer 1

The best statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates is:

Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.

This response indicates that Ruby is conducting a systematic and comparative assessment of multiple species under controlled conditions, which is essential for drawing valid conclusions. Additionally, finding a journal article suggests that she is referencing credible scientific literature to support her investigation, enhancing the reliability of her findings.
